[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] As Figures 1 to 7 shown, the present utility model provides a rapid filter bag replacement structure for a bag filter, including an installation block 4. A knob 11 is rotatably provided on the inner top surface of the installation block 4. A main gear 13 is fixedly provided at the bottom of the knob 11. A sub-gear 14 is meshed with the outer side of the main gear 13. A rope 10 is penetrated through the inside of the sub-gear 14. The wire threading hole 9 is penetrated through the outer side of the rope 10. A rotating block 6 is fixedly provided on the top surface of the wire threading hole 9. The outer side of the rotating block 6 is rotatably provided with a wire passing shaft 5, and the wire passing shaft 5 is fixedly connected with the installation block 4. By rotating the knob 11 to drive the rope 10, a plurality of rotating blocks 6 are pulled to form a circle, or the rope 10 is loosened to enable the plurality of rotating blocks 6 to become loose, so as to replace the bag sleeved on the outer side. While ensuring the firm installation of the filter bag, the installation method of the filter bag is made simpler, thereby reducing the time consumed during the installation of the filter bag and improving the work efficiency at the same time.
[0026] Specifically, an elastic shaft 12 is fixedly arranged in the middle of the knob 11. The elastic shaft 12 has a certain elasticity, which can ensure that it will not be easily broken.
[0027] Furthermore, a limiting groove 15 is fixedly arranged inside the mounting block 4, and the limiting groove 15 is in interference connection with the elastic shaft 12. After the knob 11 stops rotating, the elastic shaft 12 can be used to limit the knob 11 and prevent it from rotating back.
[0028] Still further, a connecting column is fixedly arranged at the bottom of the main gear 13, and the connecting column is rotatably connected with the mounting block 4. The connecting column is used to support the main gear 13 to ensure its normal operation.
[0029] It is worth noting that a soft rubber sleeve 16 is fixedly arranged on the outer side of the wire passing shaft 5. The material of the soft rubber sleeve 16 is rubber. The soft rubber sleeve 16 is soft in texture and can change with the change of the rotating block 6. At the same time, it is used to protect the rotating block 6 from other interferences during movement.
[0030] It should be noted that an annular sleeve 2 is attached to the outer side of the soft rubber sleeve 16. A filter bag body 1 is fixedly arranged on the outer side of the annular sleeve 2. A framework 3 is attached to the inside of the filter bag body 1. The framework 3 is used to expand the bottom of the filter bag body 1.
[0031] It is worth introducing that a mounting sleeve 7 is fixedly arranged on the outer side of the rotating block 6. A mounting shaft 8 is attached to the inside of the mounting sleeve 7. The mounting sleeve 7 and the mounting shaft 8 are used to ensure the connection and rotation between the rotating blocks 6.
[0032] Among them, the main gear 13 and the auxiliary gear 14 are prior arts and will not be elaborated here; at the same time, the present utility model also includes a power source, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here; the "front, back, left, and right" perspectives of this device are based on Figure 1 the direction shown in the drawing.
[0033] Working principle and process:
[0034] When replacing the filter bag body 1, first, rotate the knob 11. The knob 11 will drive the main gear 13 to start rotating. The main gear 13 drives the outer sub-gear 14 to start rotating. The sub-gear 14 simultaneously drives the rope 10 at the bottom to start rotating. While rotating, the rope 10 will wind or unwind on the outside of the bottom of the sub-gear 14. When the rope 10 moves, it pulls the outer rotating blocks 6, causing multiple rotating blocks 6 to form a circle and simultaneously support the outer annular sleeve 2. When released, all the rotating blocks 6 will be released simultaneously, making it easier to replace the filter bag body 1. The skeleton 3 attached inside the filter bag body 1 is used to support the bottom of the filter bag body 1. The reinforcing ribs outside the knob 11 can increase the friction during rotation. The soft rubber sleeve 16 provided outside the rotating block 6 is soft in texture and can change with the change of the rotating block 6. At the same time, it is used to protect the rotating block 6 from other interferences during movement. An installation sleeve 7 is provided outside the rotating block 6, and an installation shaft 8 is provided inside the installation sleeve 7 to ensure the connection and rotation between the rotating blocks 6. The wire threading holes 9 on the bottom surface of the rotating block 6 facilitate the rope 10 to pass through and simultaneously control all the rotating blocks 6. The elastic shaft 12 in the middle of the knob 11 is engaged with the limit groove 15 inside the installation block 4 and can be used for limiting after stopping rotating the knob 11. The wire passing shaft 5 provided outside the installation block 4 not only ensures that the rope 10 will not be interfered by others during movement but also plays a role in supporting the rotating block 6. The present utility model improves the structure on the basis of the traditional structure. While ensuring the firm installation of the cloth bag, it makes the installation method of the cloth bag simpler, thereby reducing the time consumed during the installation of the cloth bag and improving the work efficiency at the same time.
